. V INVENTOR@I777 I Patented June 14, 1938 UNITED STATES PATENT OFFICE 5 Claims.

My invention is a closure and ejector for a container and is arranged to eject a desired amount of the contents of the container when the closure is removed from the outlet of the container.

Another object is toprovide a device which ejects several successive amounts of the contents of a container by a single operation of the device.

A further object is to provide a device which will agitate the contents of a container and thereby accumulate the contents ready for ejection.

A considerable variation in form is possible with my new invention and in the accompanying drawing some of those forms are illustrated.

In the accompanying draWing,-

Fig. I is a sectional view of a portion of a container showing the closure and ejector in non ejecting position.

Fig. II is a sectional view taken on line IIII of Fig. I.

Fig. III is a side elevation, partly in section, of the container shown in Fig. I, showing the closure removed therefrom and the ejector in operation.

Fig. IV is a sectional view of a portion of a container and another form of ejector.

Fig. V is a sectional view of a portion of a container showing the closure and ejector in nonejecting position similar to Fig. I but showing another form of ejector and means for operating same.

Fig. VI is a top plan view of Fig. V.

Fig. VII is a sectional View of the container shown in Fig. V showing the closure removed from the outlet and the ejector in operation.

Referring to the numerals on the drawing, in Figs. 1, II and III a container is indicated by I, with an outlet 2, a closure 3 for the outlet 2, an ejector comprising bars 4 secured to closure 3, and plates 5 secured to bars 4.

In Fig. IV the container 6 has an outlet 1, an outlet closure 8, a bar 9 secured to the closure 8, and a cupped ejector l secured to the bar 9.

In Figs. V, VI and VII the container II has an outlet 12, an outlet closure l3 which has an arm l4 terminating in a tab l5. The arm M is pivotally mounted on the container II as shown at It, a spring I? normally holds the closure [3 against the outlet l2, a bar i8 is secured to the closure l3 and ejector plates. H] are secured to the bar l8.

As shown in Figs. I, II and III operation is accomplished by holding the container l in approximately the position shown in Fig. III and gradually pulling out the closure 3. The space between the ejector plates 5 may be equal to or less than the length of the outlet 2 and by gradually pulling the ejector from the container the contents will be ejected in several amounts, each equal to the amount between the plates 5 and each succeeding plate 5 will prevent any more of the contents from coming out'of the container until the ejector is pulled farther out. The ejector may have only one plate 5 and the operation would be the same but the amount of contents ejected from the container I would depend upon the angle of the container and the distance the ejector is pulled out of the container, especially so if the contents are of an easy flowing type.

As shown in Fig. IV the container 6 may be in a vertical position as shown and the closure 8 pulled up and thereby raising the bar 9 and ejector ID, with a portion of the contents, through the outlet 1, the amount of contents removed from the container 6 will be that which the ejector I0 is capable of retaining.

As shown in Figs. V, VI and VII the container H is held in the position shown in Fig. VII and pressure on the tab I 5 removes the closure l3 from the outlet l2, thereby pulling the bar l8 and ejector plates l9 through the outlet l2 with the same efiect described in connection with Fig. III. The ejector bar l8 and plates l9 tend to agitate the contents of the container ll thereby causing an accumulation toward the outlet l2. Only one of the ejector plates l9 may be used instead of a plurality as shown, with the same effect as described in connection with Fig. III. By releasing pressure on the tab IS the spring I! actuates the arm l4 and forces the closure l3 against the outlet [2.

My invention is susceptible of various other modifications which will be apparent to anyone skilled in the art.

What I claim is:

1. An ejector for a container having a discharge opening, said ejector comprising a closure therefor, means for moving the closure to and from the opening, members attached to the closure and extending into the container and movable in and out of the container in accordance with the movement of the closure to and from the discharge opening, and blades in spaced relationship with one another mounted on said members, said blades serving to expel products in the container to and out of the discharge opening.

2. An ejector for a container having a discharge opening, said ejector comprising a closure therefor, supporting means attached to the closure and extending into the container and movable in and out of the container in accordance with the movement of the closure to and from the discharge opening, and a blade mounted on said supporting means, said blade serving to propel products in the container to and out of the discharge opening.

3. An ejector for a container having a discharge opening, said ejector comprising a support member, a plurality of measuring members mounted on the support member and moving one after another toward and through the discharge opening as the support member is moved out of the discharge opening.

4. An ejector for a container having a discharge opening and a closure therefor, a plurality of blades attached to the closure, said blades being spaced from one another and being spaced consecutively from the closure, and being arranged to move toward and through the discharge opening one after another when the closure is removed from the discharge opening, and when passing through the discharge opening having their planes at substantially right angles to the axis of the discharge opening.

5. An ejector for a container having a discharge opening and a closure therefor, a plurality of measuring members attached to the closure and normally residing in the container when the closure is in a position closing the discharge opening, said measuring members being spaced in consecutive order from the closure and designed to draw measured amounts of products in such container to and out of the discharge opening, the amounts measured being the quantity of products entering between the respective measuring members.
